the following is a specification.

e Be a known the LHMN Bm, a citizen of the United States, and resident of Detroinfin` the -county 'of'Wayne and State -of Michigamhave invented new and useful Improvements in. Fountain Pens, of which invention relates to Afoun and more particularly to the automatic {illing mechanism thereof.

Y vThe 'principal object Vof" my invention isv the provision ofaself-lling fountain pen that can be quicklyy'filled` without immers'- ing thepen point in the ink-well or other supply of ink. 1 'l I Another object of the invention is the' arrangement of-an apertured cap at the rear extremity of the pen so as to telescope Within the main barrel, the vcap bein arranged to .receive inkby gravity from t eink-well as longhas the apertures therein are uncovered by e barrel and then to act as a.v trap lfor the ink when the apertures are so covered by.

the barrel.

A further object of. the invention is the Y provision of means for automatically filling through a fountain n from the'rear end thereof without relying upon suction or a vacuum.

Other andl advantages will be apparent frointhe following description,

wherein reference is made to the accom anying drawings illustrating a preferre ein- -`bodimentof my invention and wherein simi# lar reference numerals designate similar throughout the several views.

' In the drawings: y

at-the' end with a feedingneck` 8 v wherebyink from the reservoir asses to the underside of the pen int 9. Since'the articuliir feeding 'mec anisin employed does not enter into the present invention, the neck 8 beenillustrated only in elevation, ity being understood that any operative form of mechanism vmay be employed for feedm 'proper y. feedi ng the ink from the reservoir w 'en the pen is being used for writing.v 'l .'The main reservoir 7 comprisesjan" clon- -gated cylinder 10 in which is secured a hollow tube 11 herein shown as having a peripheral aperture 12 adjacent its forward elxtremityanld a centrally apertured block 13 at its rear extremity adapted to completely e v cylinder 10.` To maintain the tube 11 centra ly ofthe cylinder 10 I provide a pair -of-oppositely extending arms 14 at the-forward extremity of l y i the tube llfand adapted to engage the innen periphe of the cylinder 10. AA cap 15 is arrange over the` cylinder 10j and within the main barrel 5 contacting at its forward extremity against the coil spring. 6 (note Figs. 1 and 6).. The periphery of the cap '15 is provided with a series 'of fillingapertures 16 through which ink from an ink' well 17 or otherink supply may iOW into 15 whenever the cap is immersed in' I preferablyv provide a lug or'pin 18 'adja- .ran a hook 19 on the 'rear extremity of -the main barrel 5 to receive the lug 18 and 'hold the -cap 'ns't rearward movement until it isdesi to replenish the ink within the 'reservoir 7.' A-When it is desired to fill my. pen, the cap 15 is rotated to release the lug 18 from vits e ement with the hook the .coil spring wardly until e are uncovered. The .rear extremity of the pen is then dip d within the ink well 17 or' other inl: supp y juntil the filling apertures '16 are below' the surface of the ink in the ink supply 17 The'ivnk'theieupon iowsby cent the rear extremity of the cap 15 and ar- 19 o'n' the bari-el, w ereupon the pressurdpf 6 forces' the cap 15 rear.

filling apertures 16 therein' Y gravity into the cap 15 filling the cap up ltothe level of the ink inthe ink well. The

main barrel 5 .is then pushed downwardly to force the tube 11 toward. the rear end of the cap and at the same time to bring the rear end of the main barrel over the filling apertures 16 in the cap. As soonas the iilling apertures 16 are covered by the main barrel, ink can escape from the cap 15 only through the tube 11, and as the tube 11 is forced toward the bottom of the cap 15 the ink trapped in the cap is forced out of the aperture 12 in the tube into the main reservoir 7 The main barrel 5 is then raised to again uncover the apertures 16' to rmit more inlrto iow from the ink supp y into the cap 15, and then the barrel is again forced downwardly t'o receive the transfer of the ink from the filling cap 15 into the main reservoir. Two or at the most three reciprocations of the barrel suio to fill the reservoir L The rear end of the pen is then removed from the ink supply and all ink on the surface'removed by wiping. lllfhe ca 15 is then pressed forwardly and parti y lrotatedto bring the. lug '18 into locking engagement with the hook 19. The pen is Ynew in position for writing. Since the block 13 is' firmly secured withi the cylinder 10 b cementing or the like, there is @possibi 'ty of leakage of the ink .A from the reservoir 7 as long as the cap 15 is held in the position shown in Fig. 2.

During the filling operation all air within the reservoir 7 is forced out through the usual feeding aperture in the neck 8 of the pen.` This escape of air at the pen pointserves to remove any obstructions that might have been lodged within the feeding aperture, and also prevents the bubbling of ink at the rear of the pen during the reciprocations hereinbefore described.

While it will be apparent that the illus- Vtrated embodiment of my invention herein disclosed is well calculated to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modificaf tion and change within the spirit and scope of the subjoined claims. i

Having described my invention, I claim* 1. In a fountain pen, a barrel, a reservoir for ink mounted substantially centrally therein, a spring arranged between the reservo1r andbarrel a-cap slidable between the reservoir and barrel and contacting the and contacti weaves spring, the cap having a filling a rture intermediate its ends adapted to e covered. by the barrel at certain positions of the cap, and a filling tube mounted in the reservoirI and open at its rear extremity to receive Yink contained in the cap.

2. In a fountain pen for ink mounted substantially centrally therein, a spring arranged between the reservoir and barrel, a cap covering the rear end of the reservoir and slidable between the `reservoir and barrel against the tension of the spring, the cap having a plurality of filling apertures intermediate its ends adapted to be' closed by the barrel at certain positions of the cap, and a filling tube mounted. in the reservoir to receive ink contained in the cap. y y

3. In a fountain pen a barrel, a reservoir for ink mounted substantially centrally therein, a spring arran eci-between the reservoir and barrel, a sli able cap snugly fita barrel, a reservoir ting at its outer periphery within the barrel the. spring, the cap having a plurality of 'lling apertures intermediate its ends adapted to be closed by the barrel at certain positions of the cap, and a filling tube mounted in the reservoir to receive ink contained in the cap.

4. In a fountain pen a. cylindrical reservoir for ink, a cap slida le over the rear end of the reservoir and having peripheral apertures therein, aY centrally apertured block closing the rear extremity of the reservoir, a filling tube fixed in the apertureof said block'and communicating with the cap, and a barrel surrounding the reservoir and adapted to cover the apertures in theY cap atcertain positions of thecap relatively to the reservoir.

5. In a fountain pen a cylindrical reservoir for ink, a cap slidable over the rear end of the reservoir and having peripheral apertures therein, a centrally a rtured block closing the rear extremity ofmthe reservoir, a filling tube fixed in the aperture of said block and communicating with the cap, a barrel surrounding the reservoir and adapted to cover the apertures in the cap at certain positions of the cap relatively to the lreservoir, and a lug and honk connection ar- Yranged to hold the cap with its peripheral apertures covered by the barrel.

In Witness whereof I hereunto set my hand.
